Amy: I guess it must have been back when I was in the Girl Sprouts.Bernadette: Girl Sprouts?Amy: My mom made it up as an alternative to the Girl Scouts. She didn't want me selling cookies on some street corner like a whore.

Amy: Okay, what is going on?Penny: We just want you to be prepared for any surprises that could happen tomorrow.Amy: What surprises?Bernadette: We don't want to spoil anything, but you should know that Sheldon said he's ready to be physical.Amy: You shut your damn mouth! You actually heard him say this?Penny: Yes, he said he wants to do something to show you how much you mean to him.Amy: I can't believe it. I don't know what to say.Bernadette: Well, we're really happy for you and we know how much-Amy: I do know what to say. Let's get me waxed!

Leonard: My point is, while you're spending all this time on your own, building computers or practicing your cello, what you're really doing is becoming interesting. When people finally do notice you, they're gonna find someone a lot cooler than they thought. And for those of you that were popular in high school, it's over, sorry. Thank you. Congratulations.

Howard: Sheldon, don't take this the wrong way, but, you're insane.
Leonard: That may well be, but the fact is it wouldn't kill us to meet some new people.
Sheldon: For the record, it could kill us to meet new people. They could be murderers or the carriers of unusual pathogens. And I'm not insane, my mother had me tested.

Sheldon: Thank you for understanding.Amy: Of course I understand. Sheldon, there's something else I've been wanting to say, but before I do, I just. I want you to know you don't have to say it back. I know you're not ready and I don't want you to say it just because social convention dictates -Sheldon: I love you, too.Amy: You said it.

Howard: So you can never take it (the sweater) off?Leonard: No.Raj: Not even to sleep?Leonard: No.Howard: So you're just an idiot?Leonard: It's called proving a point.Howard: Is the point you're an idiot?
